Hi Jeff, I want to setup a message passing programming environment on Simics, a hardware simulation software. Simics have some pre-built target machines, ready to use, unfortunately these targets have old OS version (Fedora 5, Red Hat 7.3).I installed mpich2 on the Red Hat and bump in some many

Question: why such an old OS? Can you upgrade it? Fedora 7.3 (which is what I assume you mean) and gcc 2.96 are pretty ancient, in computer software terms -- gcc 2.96 is *over 12 years old*. That's an eternity. Additional suggestion: we haven't tested with gcc 2.96 in quite a while, and don'

If you're going that route, we're probably better off using your original "hash" based solution so people can just assign a character string to "point" to their block of data. Otherwise, we get into the problem of potentially overlapping indexes with people on branches. On Oct 3, 2012, at 7:29

In the case such a functionality become necessary, I would suggest we use a mechanism similar to the attributes in MPI (but without the multi-language mess). That will allow whoever want to attach data to a hwloc node, to do it without the mess of dealing with reserving a slot. It might require
